Abstract (en)
[origin: WO2018025065A1] Methods and apparatuses for updating multiple multiprotocol label switching (MPLS) bidirectional forwarding detection (BFD) sessions are described. In response to determining that an MPLS BFD session is in an up state, an egress network device (ND) determines whether the MPLS BFD session is part of a plurality of MPLS BFD sessions; and responsive to determining that the MPLS BFD session is part of the plurality of MPLS BFD sessions, the egress ND transmits towards an ingress network device a BFD control packet including an ingress group identifier that uniquely identifies the plurality of MPLS BFD sessions at the ingress network device, and where the transmitting the BFD control packet causes an update of a set of two or more of MPLS BFD sessions from the plurality of MPLS BFD sessions identified based on the ingress group identifier.
